Almost impossible to get legit but rather easy too boost. Start a Death Match game with increased damage, decreasing shields and increased resources. When the game starts make sure the player that is going for the achievement (Player 1) need max out the attack resource (red) and get two stars in defence (green). The other player (Player 2) need to max out the attack and defence resource. Now Player 1 will attack Player 2 with his missile and Player 2 will deflect it. Before Player 1 is killed by this missile Player 2 will attack with a second missile. When both missiles is in the air Player 1 should use his Zap (2 star defence ability). Player 1 will now die from his/her own missile and the second missile will be slowed down. Player 1 will have to puzzle his way back into the game really fast before the missile reach the target. When Player 1 returns to life he/she should just do any kind of action, attack the other player, use a power up or disrupt. This action will turn of the invincibility you get after respawning and you will be killed by the missile and the achievement should pop.
